The Wonder of Stardom Championship (ワンダー・オブ・スターダム王座, Wandā Obu Sutādamu Ōza) is a women's professional wrestlingchampionship owned by the World Wonder Ring Stardompromotion. The title, which in Stardom's championship hierarchy is situated as the secondary title behind the World of Stardom Championship, was introduced on June 26, 2011, and the inaugural champion was crowned on July 24, 2011, when Yuzuki Aikawa defeated Yoshiko in a decision match. The title is often referred to simply as the "White Belt", a name famously used by All Japan Women's Pro-Wrestling (AJW) to refer to its All Pacific Championship. The title belt was crafted by American company Top Rope Belts based on designs sent by Stardom, with a conscious decision to imitate the AJW title belt in terms of its color, with Stardom president Rossy Ogawa referring to the promotion's heyday as the "Golden Age of Joshi Puroresu". The original title belt was awarded to undefeated inaugural champion Yuzuki Aikawa, when she retired from professional wrestling on April 29, 2013. It was replaced that same night by a second identical title belt.
